Sorry to resurrect this thread but I'm still a little confused over connection to a future processor.

But to bring you up to date I now have a pair of DSP5000s, an AC12 and an MS200 and I couldn't be happier. I've also managed to figure out how to output a Chromecast Audio to the second digital input on the speakers. Couldn't be happier.

But, probably being very stupid here, but I've realised I don't know how to connect a future 568.2 - which is away from the listening area - to the speakers. Googling various stuff, I think I need a very long coaxial cable. Is that right? And is there any problem with co-axial over several metres?

Thanks.
